FORWARD AND REVERSE FRIOTION-GEARING.

Specification of Letters Patent.

Patented Aug. 15, 1916.

This invention comprises a device for winding sheet metal and for analogous purposes, such as for winding wire, cloth,etc.; but it relates more particularly to a device for winding sheet brass or other metal so as to be ready for commercial use.

The mventlon consists 1n a .devlce comprising at least three frictional gearing elements to one of which is attached a winding drum or spindle, one, two or all of said elements being so mounted as to enable the motion to be transmitted to the driving spindle from one of such frictional gearing elements, either direct or through the medium of the other gearing element for the purpose of reversing the motion of the driving spindle. The frictional gearing devices we prefer take the form of metal rolls having grooves or corrugations in their peripheries which are adapted to cooperate with each other. Two of the rolls we prefer to provide of the same formation and having a number of small or minor corrugations in their periphery and one or more large or major corrugations with which cooperates a conical or V-ridge provided upon the third roll so that when the direct drive is employed from the first roll to the second the small corrugations thereon mesh with each other, whereas when the reverse drive is employed the V ridge of the third roll meshes with the large corrugations of the first two members. To one of the first two rolls we prefer to attach the driving pulley or drum and this roll we prefer to mount eccentrically in its bearings so as to be capable of moving out of engagement with the second roll, and the third roll we prefer to so 111011111] as to be. capable of a certain amount of displacement in order to cooperate with both of theother tw o rolls and produce the reverse drive; I

The invention also comprises an improved construction of winding spindle whereby the metal, when it has been wound thereon, can be easilywithdrawn and without the usual difficulty when the metal is tightly wound.

It will be understood that the invention may take several forms, but for purpose of example we will describe one construction which isa convenient and preferred embodiment of. the invention. This construction is illustrated in the drawings, and in these drawings: Figure 1 represents in elevation a side view of the device. Fig. 2 illustrates an. end view looking in the direction of the arrow 2 in Fig. 1. Fig. 3 is a plan view of the same. Figs. 4 and 5 represent respectively diagrammatical views showing the device in the condition of the direct drive and of indirect or reverse drive respectively' Fig. 6 is a side view partly in section of, our. improved construction of winding spindle.

In the vertical sides or standards 1 are mounted three rolls 2, 3, and 4;, and the roll 2 is formed integral with a driving pulley 5 whereby power is transmitted to the device by means of a belt as in the usual manner. The rolls 2 and 3 are of similar formation and have a number of minor or small corrugations'fitand 6 upon their periphery and each has a large or major corrugation 7 and 7? respectively at about the mid-point of such periphery. The spindle 8 of the roll 2 is mounted eccentrically in its bearings asshown clearlyin Fig. 1. The spindle 8 is oscillated by the hand lever 9 and the roll 2 is moved according to the amount of eccentricity of the bearings. The roll 3 and its spindle 10 are mounted concentrically and the spindle 10 is formed with a prolongation portion 11 (see Fig. 6) to which is attached the winding drum or spindle. Below the two rolls 2 and 3' ismounted a further roll 4 which comprises a cylinder, the periphery of which is of conical or V formation and adapted to coiiperate with the large corrugations 7 and 7 of the rolls 2 and 3 when in the operative conditiene sp ndle 12 9 this 1 is ted in elongated bearings provided in the standards 1 and a forked member 13 is provided, the extremities of which have suitable bearings which surround the spindle 12. This member 13 may be operated either as shown, by means of a horizontal foot lever 15 or by means of any suitable formof hand lever and operating connection.

-When the fork member 13 is operated the spindle 12 of the roll 4 will be raised or lowered so as to engage or disengage the conical periphery of the roll with or from the grooves 7 and 7 In operation the drum 2 is rotated by means of the belt pulley 5 in the direction shown by the arrow in Figs. 1, 4, and-5. As shown in Figs. 1 and 4 the roll 2 is in en gagement with the roll 4: which in turn is in engagement with the driven roll 3. If it is desired to rotate the roll 3 in the oppo' site direction (as shown in Fig. 5) the hand lever 9 is swung to the position opposite to that shown in Fig. 1 so as to bring the corrugations 6 into mesh with the corrugations 6 and drive the roll 3 direct, the

roll 4 being of course maintained out of engagement. WVhen the roll 3 1s being rotated 1n the same direction as the roll 2,

this latter is retained in the position shown in Fig. 1', the foot lever 15 being depressed so as to raise the roll 4 and force the coni cal periphery thereof into engagement with the large corrugations '7 and 7 of the two rolls.

As shown in Fig. 4 the roll 3 is being driven direct whereas in the arrangement shown in Fig. 5 the roll 3 is being driven in the direction shown in Fig; 1 that is the reverse direction.

It will be understood that by employing a; friction drive it will be possible by varying the amount of friction grip to vary correspondingly the relative speeds of rotation of the rolls and this is advantageous since supposing the roll 2 were driven by means of a belt at the ordinary speed, the roll 3 wouldv be driven at a speed much in excess of that necessary or desirable for winding the metal. In our device however, by varying the position of the weight 9 of the hand lever 9 or by varying the amount of this weight the measure of friction between the two gripping surfaces of the rolls 2 and 3 may be altered at will, thereby bringing about a corresponding increase or decrease in the speed of rotation of the roll 3. In the reverse drive the same effect can be obtained by varying the position of the weight 15 upon the foot lever 15.

The winding spindle shown in Fig. 6 comprises two halves, the first half 16 of which is mounted rigidly upon the collar or extension member 11 of the spindle 10 and the other half 17 is pivoted at 18 to a lug or projection mounted upon the collar 11. The outer extremity of this pivoted half 18 is provided with a recess 19 in which is disposed a cam member 20 pivoted at 20 and having an extension 21 which serves as a trigger or lever whereby the cam member 20 may be operated and swung around its pivot. The metal spring member 22 is screwed to the portion 17 and its extremity bears against the cam 20.

A convex face 25 is provided upon the stationary or rigid half 16 and with this is adapted to cooperate the two faces of the cam member 20 which are at different distances from the pivot 20 thereof. In the position shown the two halves are in the separated condition, but upon swinging the trigger 21 upwardly the other face of the cam 20 will be brought adjacent to the convexface 25 and the two halves collapse so that the metal which is wound upon the spindle may be readily withdrawn without any difliculty whatever.

IVhat we claim then is:

1. A metal winder including three friction rolls, the first and second being of similar formation and having grooved peripheries adapted to engage each other when the direct drive is being transmitted from one roll to the other; driving means in conjunc tion with the first roll; the third roll having a conical periphery adapted to engage with a correspondingly shaped groove in the first and second rolls; and means whereby the third friction roll may be moved into engagement with the other two rolls to drive the second roll indirectly.

2. A metal winder including three friction rolls, the first and second being of similar formation and having V grooved peripheries adapted to engage each other when the direct drive is being transmitted from one roll tov the, other, driving means in conjunction with the first roll; the third roll having a conical periphery adapted to engage with a correspondingly shaped V groove in the first and second rolls; and means whereby the third friction roll may be moved into engagement with the other two rolls to drive the second roll indirectly.

3. A metal winder including three friction rolls, two of which are of similar formation and are provided with a series of minor grooves and with a major groove; the third roll being provided with means whereby it may be brought into engagement with the first two rolls and having a conical periphery adapted to engage with the major groove in the said two rolls.
